malheureusement
Sinon, tu te mets à la programmation, et tu fais tes propres pilotes 
Bonjour, j’ai eu ce problème sur un portable, le coupable sur ma machine était secure boot. Tu vas dans le BIOS et tu désactive secure boot, tes pilotes ne sont certainement pas signés.
Cordialement.
Je l’ai fait mais c’était idem
lspci ?
Pardon lspci
il vaut mieux dans ce cas signer les pilotes. D’autant que ça se voit dans dmesg qu’il y a un problème de signature de pilotes.
Et il n’y a aucune raison que le pilote ne soit pas signé s’il a été installé avec apt.
Supprimer Secure Boot est une erreur, car on diminue drastiquement la sécurité du système.
Pour le moment je ne dispose pas du poste en question, il est chez un ami, mail le dernier

C’est sur ça qu’il faudrait regarder de près.
Ta carte Wi-Fi est une MediaTek MT7902 (sous-ensemble AzureWave 1a3b:5524).
Sous Linux aujourd’hui, il n’existe pas de pilote amont fonctionnel pour le MT7902, d’où nmcli sans Wi-Fi et le périphérique PCI « [disabled] / IRQ 255 » (carte détectée mais sans driver lié).
Pourquoi ça coince ?
Le MT7902 n’est pas pris en charge par mt76 (les puces proches comme MT7921/7922, oui, mais pas 7902). Un patch RFC a été proposé en juillet 2025, signe que le support n’est pas encore intégré aux noyaux distribués.
De multiples retours d’utilisateurs sur Ubuntu/Mint/Manjaro confirment l’absence de support (carte vue par lspci, mais pas d’interface Wi-Fi).
